OIL-BURNER.

To all whom itpmcy concern Be it known that I, EDWARD A. Hnnmno TON, acitizen of the United States, residing Another aim of the invention isto pro-- vide in a device of this class a novel form of burner head ornozzle which may be readily cleaned in the event that the same becomesclogged. i

Another aim of the invention is to provide a novel arrangement of thesteam and liquid fuel. supply pipes which will permit of the fuel supplypipe being cleaned whenever desired without the necessity of separatingthe several parts of the structure.

In the accompanying drawings:

Figure 1 is a side elevation of the burner embodying the presentinvention;

Fig. 2 is a vertical sectional view therethrough.

Fig. 3 is a perspective view of the discharge end of the fuel tube ofthe burner nozzle.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

In the drawings the numeral 1 indicates a liquid fuel supply pipe whichleads from any suitable source of supply and which is provided with abranch 2 provided at its end with a T indicated by the numeral 3 thesaid branch entering one end of the T and the T being provided at itsother end with a plug closure 4- which may be removed if it is desiredto clean the branch other than in a manner to be presently described.The numeral 5 indicates a steam supply pipe which is connected by a T 6with branches 7 and 8. The branch 7 opens into the casing 9 of a cut-offvalve of the ordinary type, this valve being provided with the usual 1handle 10 permitting of its ready manual opening and closing. The pipe 1is provided with a short branch 11 which also communicates with thevalve casing 9 and Specification of Letters Patent.

Application filed August 2, 1916 Patented Aug. 21, 1917.

Serial No. 112,770.

by reference to Fig. 2 of the drawings it will be understood that whenthe valve proper, which is indicated by the numeral 12 is closed nosteam can enter the branch 2 of the pipe 1 by way of the valve casing.However, under conditions to be presently explained the valve 12 is tobe opened for the purpose of admitting steam to the said branch 2 of thepipe 1.

The burner proper includes a connection 13 into which is fitted the endof the branch 8 which leads from the supply pipe 5 and threaded throughthe lower end of the said connection 13 is the lower end of the fueltube of the said burner this tube being indicated by the numeral 14:.The lower end of the said tube lt extends below the lower end of theconnection 13 and is threaded into the branch of the T 3. Threaded intothe upper end of the connection 13 is the lower end of the steam tube ofthe burner indicated by the numeral 15 and connected to this tube at theupper end thereof by a mechanical expedient, the head may be consideredintegral throughout for convenience in describing the same. The head isindicated in general by the numeral and the lower portion thereof isprovided with a neck 21 which is exterior-1y threaded as at 22 andfitted to the said neck is a collar 23 having an inwardly projectingflange 24 which engages beneath the enlargement 18 of the member 17 theneck 21 of the burner head at its lower end being interiorlycircumferentially beveled as at 25 and the said bevel seating againstthe convex surface 19 of the enlargement 18 thereby forming, when thecollar 23 is tightened, a steam-tight fit between these parts.

By reference to Fig. 2 it will be observed that the fuel tube 14 extendsupwardly through the tube 15 and at its upper end eX- tends into theneck of the burner head 20, the tube 15 being internally of a greaterdiameter than the exterior diameter of the tube 14 so as to permit ofthe flow of steamtherethrough to the burner head,

I Fitted to the upper end of the fuel tube 1 1 is a discharge tip 26 thetip being preferably removably threaded onto the said end of the tubeand being provided with a closed top 27 and in its opposite sideswitlrdischarge orifices 28 preferably in the nature of narrow slots.Theburner head 20 is substantially dome-shaped its larger end being ofcourse its upper end and consequently as steam passes up through thetube 15 and past the tip 26 it is permitted to expand within the'saidburner head. The flow of steam past the said tip will of course induceflow of liquid fuel through the orifices 28 of the said tip into thehead and the steam will of course vaporize the fuel before it issuesfrom the head. In the present instance the vaporized fuel is dischargedfrom the burner head in a sheet or film and in order that this maybeaccomplished the head is provided in one side with a discharge ,orifice29 which extends a greater ,or less'distance around the said head andwhich,like the orifices 28 ispreferably in the nature of a relativelynarrow slot, It will be apparent that prior to discharge of the fuelthrough the orifices 28, the fuel as it passes upwardly through the tube14 is subjected to the heating action of the steam Within the tube 15and therefore it is more readily. vaporized,

Ccpies pf this patent may be obtained for .out through the tip 26 anyaccumulations within the said branch 2 and the fuel tube.

Having thus described the invention, what isclaimed as new is:

In a liquid fuel burner, a steam tube, a

union having an upstanding branch, a lat eral branch, and a downwardlyextending branch, the steam tube being fitted at its lower end into thefirst-mentioned branch of the union, a steamsupply pipe fitted into thelateral branch of the union, a hollow mixing head fitted to and incommunication with.

the steam tube at the upper end thereof and having a{ discharge orifice,a fuel supply pipe fitted at its lower end in the downwardly extendingbranch of the union and extending upwardly within the union and withinthe steam tube and spaced from the walls of the steam tube, the upperend of the fuel tube extending within the mixing head and providedwith'adischarge orifice, and a fuel supply pipe communicating with the lowerend of the's'aid fuel tube.

In testimony whereof I affix mysignature.
